Protein Structure Utility - Birkbeck MSc

This website and database was developed as part of an MSc thesis in Bioinformatics and Systems Biology (2020)
The database contains 3434 high resolution structures with resolution <= 1.3Å and 2697 structures from 2019 > 1.3Å
The website allows production of geometric plots and statistical analyses using these structures and selected criteria.
A highlight is the demonstration of the bimodal nature of tau.

PsuGeometry

This is a python library to produce geoemntric analyses of protein structures, including the secondary structure information from dssp and the electron density information from ccp4 files where available. The images produced range from a simple Ramachandran plot than can be coloured on for example secondary structure, electron density or B-Factor, to say, a correlation of number of electrons against B-Factor. The library contains some pre-created reports so the code to create seom fairly involved reports is minimal.

Density Flight

Density Flight is a windows application to view the inside of an electron density matrix. The application allows you to navigate around like a flight simulator, viewing atoms, bonds between atoms, finding density peaks, rotateing in the space to seek planar atoms.
The application can currently be downloaded from github and built in Vsiual Studio 2019 (C#)
It will be available for beta testing in the windows store shortly.
